MQ sensors, including the MQ3 sensor, have the ability to detect various gases. The MQ3 sensor is specifically designed to detect alcohol vapors. This means it is sensitive to alcohols such as methanol, ethanol, and isopropanol. The MQ3 sensor is commonly used to measure the concentration of alcohol in the air and is a useful tool for alerting to the presence of alcohol in the surrounding environment.
It is important to note that MQ sensors are not specific to only one gas and can react to other gases besides those they are specifically designed for. Therefore, it is important to use the MQ3 sensor exclusively for alcohol detection and to follow the manufacturer’s instructions to achieve optimal accuracy and reliability of measurements. It requires a short heating time to function correctly.
The breakout board works with both digital (DO) and analog signals (AO). The digital output is obtained by setting a threshold value with a potentiometer. The analog output will differ depending on the intensity of the gas in the sensor’s environment.
Product usage tips:
When gas is detected, the LED will start glowing. It will remain off if it doesn’t detect anything. Two mounting holes enable easy mounting to surfaces. The board comes with four male headers that need to be soldered.
MQ sensors, including the MQ2 sensor, have the capability to detect various gases.

A PIR (passive infrared) motion sensor is a device that detects physical movement within its field of vision by sensing changes in infrared radiation. This sensor works on the principle of detecting thermal thermal signals emitted by objects, mainly warm-blooded creatures like humans. The “passive” in the name refers to the fact that the sensor itself does not emit or radiate any energy for detection.

Wherever there are infrared waves, the sensor will detect them (including those from the sun). Using the built-in comparator on its outputs gives either digital (HIGH / LOW) or analog (0V-5V) signals, depending on the intensity of the IR radiation.
Light is one of the most important things in the life of most living beings. Because of this, it is common to work with light sensors when learning about electronics. The simple light sensor features a light-dependent resistor (LDR) and a sensor on a small breakout board for easier connection. As the name suggests, the LDR will change its resistance depending on the amount of light it’s exposed to. The amount of light and resistance are inversely proportional. The more light it’s exposed to, the less resistance it will have. Thus, if there’s more light, the board will have a resistance of a few hundred Ohms. If the resistor is in the dark, it will have a resistance of several thousand Ohms.
The main benefit of this board is ability to give analog and digital output. By setting the potenciometer on the board, you are able to get digital signal at the DO pin when signal crosses certain value, while analog values will be present on the AO pin at all times.
